EMCORE PB7100 Frequency Domain Terahertz Spectrometer

EMCORE’s versatile PB7100 Spectroscopy Platform is designed for scanning complex compounds to precise specifications with greater accuracy and control.

Designed for THz researchers and application developers who need to study the properties of materials at THz frequencies with high-resolution, but who don’t want to design and build their own high-resolution THz spectroscopy system. The PB7100 can sweep from 100 GHz to 2.0 THz in a single rapid scan with frequency resolution better than 0.25 GHz.

The PB7100 employs precisely tuned semiconductor DFB lasers, advanced photo-mixing source and detector, and sophisticated digital control hardware and software to provide a fully turn-key laboratory THz spectrometer system. The room temperature solid-state homodyne detection technique results in a system NEP of 10-12 W/Hz without the need for cryogenics. The highly efficient CW nature of the photo-mixing source puts all the THz power at the frequency of interest, yielding excellent signal-to-noise ratio of 60 dB-Hz at 1 THz.

And, unlike prior time-domain systems requiring complicated mode-locked lasers, the tunable semiconductor laser diodes in the PB7100 can support linear scans or can ‘frequency hop’ between frequencies of interest to scan specific regions of the spectrum with varying degrees of resolution. The separate source and detector heads may be configured to make measurements in transmission or reflection configurations.

The EMCORE PB7100 advantage

With a wide variety of Spectrometer platforms available, only EMCORE offers a modular photonic solution with such a broad range of capabilities. The platform is turn-key, simplifying setup and installation, so you can start sampling complex compounds almost immediately. The custom nature of the PB7100 allows for many scanning options including: Continuous rapid scanning from 100 GHz to 2 THz, Frequency hopping for customized scans, Active frequency monitoring, Precision scan resolutions better than 0.25 GHz & Adaptable THz optical layout .
